A small ready to copy Python Flask api. I use this when I need a simple proxy for my fontend app to consume.

app.py

from flask import Flask, jsonify, request
from flask_cors import CORS
import requests

# RUn the app by running flask run -p 3000 you can change the port number if have allready something running on port 3000

app = Flask(__name__)
# Allow CORS on every request
CORS(app)

@app.route('/', defaults={'path': ''})
@app.route('/<path:path>')
def index(path):
    return "Little api"


@app.route('/api/v1/my-method')
def get_some_data():
    url = "https://api.sampleapis.com/beers/ale"
    payload={}
    headers = {}
    response = requests.request("GET", url, headers=headers, data=payload)
    return jsonify(response.json())
